Fold a Five Intersecting Tetrahedra Dodecahedron

This is an instructional video on how to fold a five intersecting tetrahedra dodecahedron, or more simply, call it a spiky ball. All you'll need for this modular origami project is ten sheets of paper in five colors and a lot of patience. Watch this video origami tutorial and ...more

Feeling ambitious? With this guide, you'll learn how to make a 3D star with five intersecting tetrahedra using origami, the traditional Japanese folk art of paper folding. For more information, including a step-by-step overview of the folding process, as well as to get started ...more

Origami purists will argue that all origami creations, no matter how complex, should be folded from one single sheet of paper, but the rules were made to be broken, right? If you've already mastered the art of one-sheet origami projects like frogs and cranes, challenge yoursel ...more

Cory has posted some great picture of Father Magnus' intersecting cubes (the great man is holding one in his right hand) - well the above is what happens when five tetrahedra intersect. It is modular origami and made from just ten sheets of origami paper. technically in a fold ...more

A source of inspiration... Models folded and photographed by Michal Kosmulski. There are only two sets of instructions on the site, but they are very well done. I wish he had covered more of the models. Here are a few I would like to tackle (I'll admit my eyes are bigger than ...more

It's Monday, which means once again, it's time to highlight some of the recent community submissions posted to the Math Craft corkboard. I also thought that we'd try and create something known as an "Orderly Tangle" or "Polylink". This week we had a few submissions based off ...more

Math Craft admin Cory Poole provided quite a few recipes for sonobe models in his blog, and I followed one to make the pentakis dodecahedron here. I wasn't that happy with my first result because the colours kept on coming out wrong—i.e. two of the same colour next to each ot ...more

Here's my Sonobe Jasmine Dodecahedron built from Imatfaal's instructions. I built it using "cheap" patterned origami paper (150 cm so I could use Imatfaal's measurements) from Michael's. I then took some silver metallic leafing paint and painted the exposed white parts with s ...more

Last post, the Sonobe unit was introduced as a way to use multiple copies of a simply folded piece of paper to make geometric objects. In this post, we are going to explore that concept further by making two more geometric models. The first is the truncated icosahedron, which ...more
